Calculate the number of equivalents in each of the following:
d. 2 moles of Fe3+

검증된 단계별 안내
1
Understand the concept of equivalents: In chemistry, an equivalent is the amount of a substance that reacts with or supplies 1 mole of hydrogen ions (H⁺) or electrons in a reaction. For ions, the number of equivalents is determined by multiplying the number of moles by the charge of the ion.
Identify the charge of the ion: The problem specifies Fe³⁺, which has a charge of +3.
Write the formula to calculate the number of equivalents: The number of equivalents is given by the equation: neq=nmoles×charge.
Substitute the given values into the formula: Here, the number of moles is 2, and the charge of Fe³⁺ is 3. So, the calculation becomes: neq=2×3.
Perform the multiplication to determine the number of equivalents. This will give you the final result.

Equivalents

In chemistry, an equivalent is a measure of reactive capacity. It is defined as the amount of a substance that can react with or replace one mole of hydrogen ions (H⁺) in a reaction. The concept of equivalents is crucial for stoichiometry, as it allows chemists to relate the amounts of reactants and products in a chemical reaction based on their reactivity.

Moles

A mole is a fundamental unit in chemistry that quantifies the amount of substance. One mole contains approximately 6.022 x 10²³ entities, such as atoms or molecules. Understanding moles is essential for converting between mass and number of particles, which is vital for calculating equivalents in reactions involving ions like Fe³⁺.

Mole Concept

Valency

Valency refers to the combining capacity of an element, often indicated by the number of electrons an atom can lose, gain, or share during a chemical reaction. For Fe³⁺, the valency is +3, meaning it can combine with three equivalents of other ions or molecules. This concept is important for determining the number of equivalents when calculating the reactivity of ions in solutions.
